Current mode torture analysis (positive voltage)

A project log for enhancement to depletion

DIY method to lower gate threshold voltage of regular MOSFETs, ultimately reversing it.

Overall torture kinetic


Rate of threshold voltage change is not exactly proportional to gate current, but close to being so.

Post-torture drift

Surprisingly little drift. But the mosfet is likely very much damaged, so it doesn't make much sense.


I have only one more fresh mosfet remaining for experimenting (same model, IPD10N03LA). I plan doing a negative voltage torturing for comparison with positive. After that, I either order more of them (if I can), or move to experimenting with other mosfet models.

UPDATE: found one more!
